Name an industry which can cause both air and thermal pollution and as well as eutrophication.
The fertilizer industry can cause both air and thermal pollution as well as eutrophication. Air and thermal pollution are caused by chemical fertiliser units, thermal power plants, refineries, smelting and metallurgical processing units, steel mills, and enterprises that use water or steam as coolants. If these industries discharge chemicals that are high in phosphate and nitrogen, eutrophication may ensue.
